Emtek LC4-DLB275R-US19 Deadlatch 2.75in Backset Flat Black

Product Description

The EMTEK LC4-DLB275R-US19 is a key-in-lever or key-in-knob deadlatch designed for residential and light commercial door hardware installations. It features a 2.75-inch backset and a 1/4-inch radius corner faceplate, finished in flat black. The deadlatch functions as the spring-actuated bolt component that keeps a door secured in the latched position until the lever or knob is operated. This part is installed by locksmiths, general contractors, and finish carpenters working with cylindrical lockset applications. The flat black finish coordinates with matching EMTEK hardware trims and rosettes.

This deadlatch is intended for use with key-in-lever or key-in-knob cylindrical locksets requiring a 2.75-inch backset. It is suited to residential entry doors, interior passage doors, and light commercial applications where a flat black finish is specified. The 1/4-inch radius corner faceplate fits standard door prep mortises that call for a radius-corner strike and latch pocket. Sold individually as a single unit replacement or new-installation component.
